A device for centralized programmable control of a group of objects operating asynchronously with various programs is known, based on the use of a control system issuing control commands taking into account the result of comparing the signal reproduced in accelerated timescale information with the signal generated by the command 1 and t2j. however, a constant adjustment of the control programs is required each time the object control law changes, and to change the programs of interconnected control objects, an introduction to the control system of computing devices is required. Autoprocessors of a multiprocess electroplating line can be assigned to these control objects, whose programs of work are strictly determined by the types of technological processes by which the suspensions with parts are processed on this line. The use of a centralized system of software control of auto-operators with relocation of control programs of auto-operators in the memory of the system requires adjustment of control programs if the line is combined processing of several suspensions with details and a previously unplanned suspension is being processed for processing. Correction of control programs as the sequence of receipt of suspensions for processing by different technological processes is disturbed requires the introduction of a computerized electronic computer operating in real time to the most complex, expensive and least reliable device. Closest to the proposed technical entity is a centralized and programmed control of auto-operators of galvanic Landa, containing a dispatch console connected through an I / O unit and a control unit with a storage device connected to the communication unit with auto-operators (Z.

After the end of the dwell time from register 20, a signal is sent to register 18 to carry out operations to move the suspension to the next position, and after moving the suspension to the last position in the process, a signal is sent from register 19 to channel 17 to release the channel to which the suspension is fixed.

Switch 7 is designed to secure the free main bath at the suspension. Typically, several baths are used on the electroplating line for the main coating process. In the process of machining parts according to different technological processes, these baths are released at random, therefore, when starting up suspensions with details for processing simultaneously with binding to the process channel, the base and main bath are loaded, into which the suspension is loaded according to the technological process. Register 8 is designed to maintain the suspension in the main bath and generate a signal to release the bath after the end of the exposure. The generator 9 is designed to form pulses with a follow-up period of 5 seconds and 1 minute to feed the input time counters and timers of the main baths. Block 10 is designed to receive commands to auto operators from node 4 with control from block b. 1 The operation of the device is as follows. Suspension with details arrives at the place of loading. On the remote control 1 dial the required technological process of processing parts. The channel number impulses from block 3 interrogate register 17 triggers, and the main baths are checked for failure. If there is an indication of a free bath coming from the switch 7 of the primary bath, the readiness of the channel, for example, the first one, on the register of channels 17, The start address of the command of the technological process dialed on the console 1 is entered into the counter of command addresses of the first channel. Thus, the selected technological process is assigned to the first channel. Simultaneously, it is fixed to the first channel and the main bath. By this, the command relating to the free main bath on the basis of the switch T is rewritten into the memory cell relating to the first channel. Then, the register 18, corresponding to the first channel, is written, and the register 17 of the first channel is entered into register 17. In the next cycle of operation of block 3, with the arrival of the pulse of the first channel, the command is read according to the content of the address located in the command address counter of the first channel. According to the contents of the command, one of the auto operators is interrogated, and if it is free, the command from register 16 is rewritten into the corresponding register of the command of block 10, and the command register of the operator without the suspension is entered into the command register. Thereafter, a recording is written into the corresponding to the first channel trigger register 19, and the trigger of the first channel in register 18 is zeroed. After the auto operator arrives at the bath specified in the command with the arrival of the first channel pulse from block 3, according to the sign contained in register 19, the contents of the address in the counter of commands of the first channel are changed and the new command is read at this address, which is written to the command register of block 10. The auto operator moves from the suspension to the next position. At the same time, the trigger 20 of the first channel in register 19 is written to, the trigger of the first channel in register 19 is zeroed, and the time code The racks are recorded in the corresponding cell of the first channel of the RAM of unit 15. After the auto operator arrives at the specified position, the hold time counter of the first channel is started according to the sign contained in register 20, and the auto operator release signal is sent to block 10. The input of the time counter from the generator 9 receives pulses with a period of 5 s or i min, depending on the exposure time. After the end of the time indicated in the code, the delay is written to the corresponding register 18 trigger register, and the first channel trigger in register 20 is zeroed. The cycle of performing the operation of moving the suspension from one position to another and exposing it to this end. Then the auto operator’s request again occurs, the suspension moves to the next position and its exposure in this position. When the command indicates that the suspension is moving, the suspension time code in the main bath is entered into the main bath time counter in register 8, the counter is turned on, and after the end of the specified hold, a release signal is sent to switch 7 baths. After the entire technological process has passed, when a sign of the last command appears in a command, a release signal of the first channel is sent to register 17. Thus, commands to auto operators (control object J is formed according to the MCLM control program describing the technological processes (control laws), as the need arises to carry the suspensions from one bath to another, and since the control programs describe the technological processes, they do not depend on the sequence the arrival of suspensions with parts for oraootku on different technological processes, there is no need to adjust them and introduce a computer into the device. device and its reliability significantly increases.
